When looking into papers describing the 922 ANSI-SCSI-standard, this assignment of drives appears to be wrong. 923 The SCSI-standard follows a hardware-hierarchy which says that id 7 924 has the highest priority and id 0 the lowest. Therefore, the host 925 adapters are still today everywhere placed as SCSI-id 7 by default. 926 In the SCSI-standard, the drive letters express the priority of the 927 disk. C: should be the hard disk, or a partition on it, with the 928 highest priority. This must therefore be the disk with the highest 929 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the 930 original definition of the SCSI-standard as also industrial- and 931 process-control-machines, like VME-CPUs running under realtime-OSes 932 (e.g. LynxOS, OS9) do. 933 934 If you like to run Linux on your MCA-machine with the same 935 assignment of hard disks as seen from e.g. DOS or OS/2 on your 936 machine, which is in addition conformant to the SCSI-standard, you 937 must say Y here.

If you say Y here, each device connected 955 to your SCSI-bus will be issued a reset-command after it has been 956 probed, while the kernel is booting. This may cause problems with 957 more modern devices, like hard disks, which do not appreciate these 958 reset commands, and can cause your system to hang.

Some SCSI 1316 devices don't implement this properly; if you want to disable this 1317 feature, enter 0 or 1 here (it doesn't matter which). 1318 1319 The default value is 8 and should be supported by most hard disks. 1320 This value can be overridden from the boot command line using the 1321 'tags' option as follows (example): 1322 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 1323 4, set queue depth to 16 for target 2 and target 3 on controller 0 1324 and set queue depth to 10 for target 0 / lun 2 on controller 1. 1325 1326 The normal answer therefore is to go with the default 8 and to use 1327 a boot command line option for devices that need to use a different 1328 command queue depth. 1329 1330 There is no safe option other than using good SCSI devices. 1331 1332config SCSI_NCR53C8XX_MAX_TAGS 1333 int "maximum number of queued commands" 1334 depends on SCSI_ZALON || SCSI_NCR_Q720 1335 default "32" 1336 ---help--- 1337 This option allows you to specify the maximum number of commands 1338 that can be queued to any device, when tagged command queuing is 1339 possible.

For example, a FAST-20 Wide 16 device is 1358 able to transfer data at 20 million 16 bit packets per second for a 1359 total rate of 40 MB/s. 1360 1361 You may specify 0 if you want to only use asynchronous data 1362 transfers. This is the safest and slowest option. Otherwise, specify 1363 a value between 5 and 80, depending on the capability of your SCSI 1364 controller. The higher the number, the faster the data transfer. 1365 Note that 80 should normally be ok since the driver decreases the 1366 value automatically according to the controller's capabilities. 1367 1368 Your answer to this question is ignored for controllers with NVRAM, 1369 since the driver will get this information from the user set-up. It 1370 also can be overridden using a boot setup option, as follows 1371 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1372 for FAST-20 synchronous data transfer (20 mega-transfers per 1373 second). 1374 1375 The normal answer therefore is not to go with the default but to 1376 select the maximum value 80 allowing the driver to use the maximum 1377 value supported by each controller. If this causes problems with 1378 your SCSI devices, you should come back and decrease the value. 1379 1380 There is no safe option other than using good cabling, right 1381 terminations and SCSI conformant devices. 1382 1383config SCSI_NCR53C8XX_NO_DISCONNECT 1384 bool "not allow targets to disconnect" 1385 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1386 help 1387 This option is only provided for safety if you suspect some SCSI 1388 device of yours to not support properly the target-disconnect 1389 feature.
